TROCCOLI, Gustavo et al. Resección de lesiones cerebrales en area rolándica con mapeo cortical intraoperatorio^*. Rev. argent. neurocir. [online]. 2006, vol.20, n.1, pp.1-6. ISSN 1850-1532.

Objective: To describe the results obtained with intraoperative cortical mapping in the surgical treatment of rolandic tumors. Method: We studied 27 patients (may 2000-may 2005) between 27 and 78 years old (16 males-11 females) with intracranial tumors located in the rolandic area. In all cases we used techniques of functional localization and, intraoperative somatosensorial evoked potentials and bipolar cortical stimulation. Results:  In 24 cases removal was total and in 3 cases was subtotal. Of the 23 cases with preoperative motor symptoms, postoperatively 17 were improved, 5 remained stable and 1 deteriorated transiently. No patient without preoperative deficits was worst. We did not have complications related to the localization procedure. Conclusion:  Intraoperative cortical mapping is a safe and sound technique for the preservation of the eloquent cortex during surgery of rolandic tumors.
